【问题描述】：

我一直在开发 ruby on rails 应用程序并尝试集成完整的日历 gem，但遇到了错误。我可以让日历显示，但不能显示模块来输入新事件，每次我修复一个错误时，我似乎遇到了另一个错误。

我目前收到一个 ActionView::Template::Error

在我的控制台中

      <div class="modal-body">
        <%= render 'form', entry: @entry %>
      </div>
    </div>
  </div>
</div>

有什么想法吗？

【解决方案1】：

这是 Rails 的魔法，当你没有为 simple_form_for 指定第二个选项（url）时，Rails 会尝试设置它，在你的情况下，<%= simple_form_for @entry do |f|%> 会被 Rails 转换为 <%= simple_form_for @entry, url: entries_index_path do |f|%>。在您的路线中，没有这样的 _path 助手（如错误所述）。要解决此问题，请运行 bundle rake routes 并设置正确的 url 选项。

Check the documentation
